MilliporeSigma™ Calbiochem™ Rad6 Inhibitor, TZ9

Description

Rad6 Inhibitor, TZ9, CAS 002789-86-7, is a cell-permeable inhibitor of Rad6B-Ub thioester bond formation and subsequent substrate ubiquitination. Directly binds to the catalytic site of Rad6B/HHR6B.

A cell-permeable triazine compound that directly targets human E2 Ubiquitin-conjugating enzyme Rad6B/HHR6B catalytic site via noncovalent interactions and effectively inhibits Rad6B-Ub thioester bond formation as well as subsequent substrate ubiquitination without affecting UbcH5B/UBE2D2-catalyzed BCA2 ubiquitination. Shown to inhibit the proliferation of high Rad6B-expressing MDA-MB-231 (IC₅₀ = 6μM in 72 h), but not the low Rad6B-expressing, non-transformed MCF10A, via G2/M arrest and apoptosis induction. Two known cellular Rad6 substrates, β-catenin and PCNA, are reported to be downregulated following 24 h inhibitor treatment in MDA-MB-231 cultures (0.5 to 5μM).
